Abstract
OBJECTIVE To understand the videonystagmography (VNG) findings in various balance disorders in 67 patients who presented to the outpatient department of an otorhinolaryngology clinic. MATERIALS AND METHODS This cross-sectional study was conducted in the outpatient department of the otorhinolaryngology clinic of a tertiary care center. A total of 67 patients between the age group of 18 and 70 years with balance disorders were included in the study. VNG findings in different balance disorders were observed and analyzed. RESULTS A total of 67 patients were enrolled in the study. Findings like caloric inversion and optokinetic nystagmus do not always indicate a central balance disorder due to technical errors and other limitations during the test. However, abnormal saccades seem to be a more relevant finding in central disorders. Rare variants of benign paroxysmal positional vertigo (BPPV) like multiple canal BPPV were also diagnosed using VNG. CONCLUSION VNG has come out as a very useful test in our study aiding in 75% of diagnoses. The overall benefits of VNG in balance disorders are immense and necessitate their inclusion in every vertigo clinic.

Abstract
Objective We aimed to evaluate the diagnostic performance of some anatomical variables with regard to endolymphatic sac (ES) and duct (ED), measured by non-contrast three-dimensional sampling perfection with application-optimized contrasts using different flip angle evolutions (3D-SPACE) magnetic resonance imaging (MRI), in differentiating vestibular migraine (VM) from unilateral Ménière's disease (MD). Methods In this study, 81 patients with VM, 97 patients with unilateral MD, and 50 control subjects were enrolled. The MRI-visualized parameters, such as the distance between the vertical part of the posterior semicircular canal and the posterior fossa (MRI-PP distance) and visibility of vestibular aqueduct (MRI-VA), were measured bilaterally. The diagnostic value of the MRI-PP distance and MRI-VA visibility for differentiating VM from unilateral MD was examined. Results (1) Compared with the VM patients, patients with unilateral MD exhibited shorter MRI-PP distance and poorer MRI-VA visibility. No differences in the MRI-PP distance and MRI-VA visibility were detected between patients with VM and control subjects. (2) No significant interaural difference in the MRI-PP distance and MRI-VA visibility was observed in patients with VM and those with unilateral MD, respectively. (3) Area under the curve (AUC) showed a low diagnostic value for the MRI-PP distance and MRI-VA visibility, respectively, in differentiating between the VM and unilateral MD. Conclusions Based on non-enhanced MRI-visualized measurement, anatomical variables with regard to the endolymphatic drainage system differed significantly between the patients with VM and those with unilateral MD. Further investigations are needed to improve the diagnostic value of these indices in differentiating VM from unilateral MD.

Abstract
Initial diagnosis of peripheral vestibulopathy requires a detailed history, physical examination, and, in some cases, audiovestibular testing, radiographic imaging, or serology. Differentiation of a peripheral vestibulopathy as progressive or degenerative is often nuanced and influenced by a characterization of a patient's symptoms or natural history over time. A diverse group of vestibular pathology may fit into this category, including Ménière's disease, autoimmune conditions, congenital pathologies, ototoxic medications, radiation therapy, and perilymphatic fistula. Differentiation among these entities may be guided by initial or subsequent symptomatology, with various combinations of audiovestibular testing, serology, and imaging. Treatment options are disparate and disease-specific, ranging from observation to medical management or surgical intervention, underscoring the need for astute investigation and diagnosis.

Abstract
Introduction Vestibular-evoked myogenic potentials (VEMPs) can be abnormal in patients with idiopathic recurrent spontaneous vertigo. We aimed to determine whether abnormal cervical vestibular-evoked myogenic potentials (cVEMPs) can predict evolution of isolated recurrent vertigo into Meniere’s disease (MD). Methods We had followed up 146 patients with isolated recurrent vertigo and an evaluation of cVEMPs for 0–142 months [median = 6, interquartile range (IQR) = 0–29] at the Dizziness Clinic of Seoul National University Bundang Hospital from June 2003 to May 2014. We defined the variables associated with a progression into MD and calculated cumulative progression rates. Results Among the 94 patients with recurrent vertigo and abnormal cVEMPs, 18 (18/94, 19%) showed an evolution into MD while only 2 of the 50 (4%) patients with normal cVEMPs evolved into MD during the follow-up (p = 0.01). The interval between onset of vertigo and development of cochlear symptoms ranged from 1 month to 13.6 years (median = 3 years, IQR = 0.5–4.5 years). Overall, pure tone audiometry (PTA) threshold at 0.25 kHz [hazard ratio (HR) = 1.1, 95% confidence interval (CI) = 1.0–1.2] and abnormalities of cVEMPs (HR = 5.6, 95% CI = 1.3–25.5) were found to be significantly associated with a later conversion into MD. The cumulative progression rate was 12% (95% CI = 5–18) at 1 year, 18% (8–26) at 2 years, and 22% (11–32) at 3 years. Conclusion Abnormal cVEMPs may be an indicator for evolution of isolated recurrent vertigo into MD. Patients with isolated recurrent vertigo may be better managed conforming to MD when cVEMPs are abnormal.

Abstract
Ménière's disease is defined as an idiopathic syndrome characterized by endolymphatic hydrops. Various tests and measurement methods have been employed for the diagnosis of Ménière's disease. These include audiological, vestibular, radiological, clinical, and biochemical tests. However, the lack of a definitive or gold standard diagnostic test sometimes complicates the process of diagnosis. Hence, the clinician should be well-experienced in deciding when to perform a test and how to interpret the results of the test. Furthermore, having the knowledge of the validity and reliability of these tests plays a critical role. This review particularly emphasizes on remarking the validity and reliability of each test performed for the diagnosis of Ménière's disease and discussing the results according to the up-to-date literature.

Recurrent peripheral vestibulopathy: Is MRI useful for the diagnosis of endolymphatic hydrops in clinical practice? Eur Radiol 2015; 25:3043-9.

Abstract
OBJECTIVES Recurrent peripheral vestibulopathy (RPV) is a public health problem, yet the aetiology remains unclear. Recent developments in MRI of endolymphatic hydrops (EH) allow for a better understanding of inner ear disorders. We intended to study the prevalence of EH in patients with RPV, in comparison to those with Meniere's disease (MD). METHODS MRI examinations were performed 4 hours after intravenous injection of gadoteric acid in 132 patients with RPV (n = 64) and MD (n = 68). Two radiologists retrospectively studied the prevalence and localization of EH in RPV and MD groups. Patients were graded based on the number and localization of hydrops, between 1 (EH in either cochlea or vestibule on one side) and 4 (EH in cochlea and vestibule on both ears). RESULTS We identified EH in 31 out of 64 patients and in 61 out of 68 patients in the RPV and MD groups, respectively. There was a significant difference regarding the number of subjects with EH between the two groups (p ≤ 0.01), with a higher average number of hydrops localization in MD group (p ≤ 0.01). CONCLUSION MRI may reveal EH in some cases among patients with RPV, suggesting a similar pathophysiological mechanism in comparison with MD. KEY POINTS • MRI may reveal endolymphatic hydrops in some patients with recurrent peripheral vestibulopathy. • We suggest a similar pathophysiological mechanism in recurrent vestibulopathy and Meniere's Disease. • MRI with delayed acquisition helps clinicians to assess patients with recurrent vestibulopathy. • The outcome would be to aid the development of adapted therapeutic strategies. • MRI of endolymphatic hydrops should probably be included in future diagnostic protocols.

Abstract
OBJECTIVE To compare the degree of sensorineural hearing loss in patients with Ménière's disease (MD) with and without hyperinsulinism by different methods of assessment. STUDY DESIGN Historical cohort study. SETTING Ménière's Disease Care and Research Clinics of Hospital de Clinicas de Porto Alegre, a tertiary care university hospital in Southern Brazil. PATIENTS Patients with a definite diagnosis of MD based on the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines. INTERVENTION Patients were assessed by glucose overload tests (5-h glucose and insulin curves) and under baseline physiological conditions (Homeostasis Model Assessment/Insulin Resistance [HOMA-IR], Quantitative Insulin Sensitivity Check Index [QUICKI], and glucose/insulin ratio). These patients underwent annual pure-tone audiometry and were analyzed using 4-tone average (FTA), that is, arithmetic mean of 500, 1,000, 2,000, and 3,000 Hz, during the third, fourth, and fifth years of disease progression. MAIN OUTCOME MEASURE Hearing loss assessed by FTA and classified in Stages I to IV (AAO-HNS). RESULTS Forty-nine (76.6%) patients were defined as hyperinsulinemic and 15 (23.4%) as normoinsulinemic. Impairment on FTA was higher in the hyperinsulinemic group (52.04 ± 17.5 versus 39.75 ± 9.20, p = 0.027) when assessed by the 5-hour insulin curve. Hyperinsulinemic subjects were 3.5 times more likely to develop hearing damage greater than 40 dB (i.e., Stages III and IV) than normoinsulinemic subjects (OR = 3.52; 95% CI, 1.05-11.76). A moderate correlation between the insulin curve and the HOMA-IR was found (r = 0.524, p = 0.001). CONCLUSION Hyperinsulinism in MD is associated with greater clinical hearing damage.

Abstract
One hundred and forty-six years after its first description, the differential diagnosis of Meniere’s disease remains very challenging. The aim of the present study is to review the current knowledge on the advantages and disadvantages of the new diagnostic methods for Meniere’s disease. The importance of accurate diagnosis for primary healthcare systems is also discussed. An extensive search of the literature was performed in Medline and other available database sources. Information from electronic links and related books were also included. Controlled clinical studies, prospective cohort studies, retrospective cohort studies, cross-sectional studies, case reports, written guidelines, systematic reviews, and books were selected. The typical clinical triad of symptoms from the vestibular and cochlear systems (recurrent vertigo, fluctuating sensorineural hearing loss and tinnitus) is usually the key for clinical diagnosis. Glycerol dehydration test and electrocochleography are the main diagnostic tests in current practice, while vestibular evoked myogenic potentials may be used in disease staging. Imagine techniques are not specific enough to set alone the diagnosis of Meniere’s disease, although they may be necessary to exclude other pathologies. Recently developed 3D MRI protocols can delineate the perilymphatic/endolymphatic spaces of the inner ear and aid diagnosis. Meniere’s disease is a continuous problem for the patients and affects their quality of life. Taking into account the frequent nature of the disease in certain countries, efforts for reliable diagnosis, prompt referral, and successful management are undoubtedly cost-effective for healthcare systems.

Abstract
OBJECTIVE To identify the predictive capabilities of caloric and rotational testing to distinguish peripheral from nonperipheral vestibular causes of vertigo. STUDY DESIGN Retrospective case review. SETTING Academic tertiary care vestibular function test center. PATIENTS Two hundred dizzy patients (132 with and 68 without suspected peripheral vestibular dizziness) evaluated with bithermal binaural caloric and sinusoidal and step-velocity rotary chair (RC) tests. INTERVENTION Caloric and RC tests. MAIN OUTCOME MEASURES 1) Receiver operating characteristic (ROC) analysis of individual caloric and rotary parameters for area under the curve (AUC) as indication of predictive value, and 2) logistic regression analysis of parameter combinations for identification of optimal test battery for predicting peripheral vestibular dysfunction RESULTS Analysis of the individual receiver operating characteristic (ROC) curves for each caloric and RC test parameter for prediction of peripheral vestibulopathy revealed that the best overall predictive parameter was percentage of caloric weakness (CW; AUC-ROC, 0.73; 95% confidence interval, 0.66-0.80). Using 29.5% as the optimal cutoff point for CW, a specificity of 84% and sensitivity of 55% were obtained. Because of the reduced AUC for the RC parameters, no optimal cutoff points were chosen. Using a logistic regression model in predicting patients with peripheral vestibulopathy demonstrated that either comprehensive caloric and RC testing or the combination of caloric and 0.025 Hz, 0.5 Hz, and time-constant rotational testing yielded the highest predictive value (AUC-ROC, 0.79) CONCLUSION Calculation of CW was the most promising single marker for identifying peripheral from nonperipheral vestibulopathic patients. Individual RC parameters showed limited predictive value to differentiate peripheral from nonperipheral vestibular dysfunction. However, the combination of subtests yielded an AUC-ROC only slightly less than caloric testing. The combination of caloric and RC testing revealed the strongest predictive capabilities for identifying peripheral vestibular injury. Furthermore, the combination of an abbreviated form of RC testing with caloric testing yielded nearly identical results as full caloric and rotational testing.

Abstract
Vestibular vertigo may be induced by increases in the endolymphatic pressure that activate pressure-dependent K(+) currents (I(K,p)) in vestibular hair cells. I(K,p) have been demonstrated to modulate transmitter release and are inhibited by low concentrations of cinnarizine. Beneficial effects against vestibular vertigo of cinnarizine have been attributed to its inhibition of calcium currents. Our aim was to determine the extent by which the inhibition of I(K,p) by cinnarizine may alter the voltage response to stimulating currents and to analyze whether such alterations may be sufficient to modulate the activation of Ca(2+) currents and transmitter release. Vestibular type II hair cells from guinea pigs were studied using the whole-cell patch-clamp technique. In current clamp, voltage responses to trains of stimulating currents were recorded. In voltage clamp, transmitter release was assessed from changes in the cell capacitance, as calculated from the phase shift during application of sine waves. Cinnarizine (0.05-3 microM) concentration dependently reversed the depressing effects of increases in the hydrostatic pressure (from 0.2 to 0.5 cm H(2)O) on the voltage responses to stimulating currents. Voltage protocols that simulated these responses were applied in voltage clamp and revealed a significantly enhanced transmitter release in conditions mimicking an inhibition of I(K,p). Cinnarizine (< or =0.5 microM) did not inhibit calcium currents. We conclude that cinnarizine, in pharmacologically relevant concentrations, enhances transmitter release in the presence of elevated hydrostatic pressure by an indirect mechanism, involving inhibition of I(K,p), enhancing depolarization, and increasing the voltage-dependent activation of Ca(2+) currents, without directly affecting Ca(2+) current.

Abstract
Meniere's disease is a chronic illness that affects a substantial number of patients every year worldwide. The disease is characterised by intermittent episodes of vertigo lasting from minutes to hours, with fluctuating sensorineural hearing loss, tinnitus, and aural pressure. Although there is currently no cure, more than 85% of patients with Meniere's disease are helped by either changes in lifestyle and medical treatment, or minimally invasive surgical procedures such as intratympanic steroid therapy, intratympanic gentamicin therapy, and endolymphatic sac surgery. Vestibular neurectomy has a very high rate of vertigo control and is available for patients with good hearing who have failed all other treatments. Labyrinthectomy is undertaken as a last resort and is best reserved for patients with unilateral disease and deafness.

Abstract
The current guidelines of the American Academy of Otolaryngology-Head and Neck Surgery entrust the diagnosis of Ménière disease (MD) only to the clinical presentation and the pure tone audiometry. However, most otolaryngologists request a widened instrumental evaluation of the patients suspected of MD. The effective reliability of the further instrumental support for the diagnosis of MD is still debated in the literature because of nonstandardized procedures and sometimes incoherence among authors. New and more sophisticated diagnostic tests have been developed both in audiovestibology and in imaging in the last few years. A review of the recent literature on this controversial subject is provided.

Abstract
OBJECTIVES To determine whether an association exists between the parameters of the caloric and rotatory chair tests in patients with unilateral Ménière's disease. METHODS Patients with unilateral Ménière's disease (n = 100) were subjected to the caloric and the rotatory chair test (sinusoidal harmonic acceleration and impulsive tests) on the same day. Canal paresis and directional preponderance were assessed in the caloric test, and different variables were measured in the rotatory chair test based on the existence of abnormal parameters in the vestibulo-ocular reflex at two or three consecutive frequencies of those tested and on the time constant of the vestibulo-ocular reflex. STUDY DESIGN AND SETTING A prospective study was conducted at a University hospital. RESULTS An abnormal result in the caloric test was obtained from 73% of the patients. In the rotatory chair test, the most frequent abnormal findings involved increases in the normal phase lead at 2 consecutive frequencies tested (23%). There was a stronger association between an abnormal result in phase, gain, and/or symmetry at three adjacent frequencies and a pathological result in the caloric test. CONCLUSION Very few of the criteria used to define the caloric and rotatory chair tests seem to be associated. This confirms previous knowledge that both tests examine vestibulo-ocular reflex by different ways. Only when vestibular dysfunction is severe enough (manifested by the finding of an abnormal result in at least three consecutive frequencies in the rotatory chair test), the caloric test is also found to be abnormal.
